Magpul MBUS GEN 2 Front Sight Review

The Magpul MBUS GEN 2 front sight is an inexpensive spring loaded AR flip up back-up frontsight. This is a rugged flip sight as it’s polymer construction resists impacts, and it’s small size makes it compatible with a wider range of optics than the bulkier, but respected GEN 1 frontsight. This flip up sight also introduces spring loading to keep it perfectly upright and thus more consistent in elevation than its predecessor. It’s also very light – a set of GEN 2 MBUS AR sights will add a negligible amount of weight to your rifle or carbine. You can mount these back up sights on any MIL-STD-1913 Picatinny rail, but this M16 foresight must be mounted on a railed fore-end not on a gas block due to obvious issues with extreme heat and polymer. The front sight adjuster tool and mounting hardware is included. The Magpul MBUS GEN2 AR back up iron sight is manufactured in black, dark earth, OD green and foliage green to suit different terrains and scenarios. These are iron sights without the iron!
